Overview
This template documents the field testing of backflow prevention assemblies and captures the information that makes the test defensible: inspection date and time, site and service address, water purveyor or AHJ, device type, manufacturer, model, size, serial number, installation location, test kit identification, calibration status, test readings, and final disposition.
Use it when a backflow preventer must be tested for routine compliance, after repair, after relocation, after a suspected failure, or before a seasonal system is returned to service. It is designed for RP, DC, DCDA, PVB, and SVB assemblies, so the tester can follow the correct sequence and record the required differential pressure, relief valve, or air inlet readings as applicable.
Do not use this template as a generic plumbing checklist or for devices that are not field-testable in the same way. If the site needs only a visual survey, a commissioning checklist, or a repair work order, this form is too specific. It is also not a substitute for local cross-connection control rules, manufacturer instructions, or the water purveyor’s required test procedure. The value of the template is that it turns a field test into a complete compliance record with clear pass/fail status, documented deficiencies, and a traceable retest path.
Standards & compliance context
- Backflow testing records are commonly required under local cross-connection control programs and water purveyor rules, which often rely on standardized field test documentation.
- The device-specific test sequence and pass/fail criteria should follow manufacturer instructions and the applicable plumbing or water-supply code adopted by the AHJ.
- Recording calibrated test equipment supports the traceability expected in regulated maintenance programs and helps defend the result during review or dispute.
- If the assembly protects a fire protection or life-safety water supply, coordinate the test with the facility’s fire protection procedures and any AHJ notification requirements.
- When a deficiency is found, the report should support corrective action and retest documentation rather than treating the failure as a final record.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
What's inside this template
Inspection Identification
This section establishes when, where, and why the test was performed so the report can be tied to the correct site and compliance requirement.
- Inspection date and time recorded
- Site name and service address entered
- Water purveyor or AHJ identified
- Test purpose documented
Device Identification
This section ties the test to one specific backflow assembly and prevents confusion between similar devices on the same property.
- Backflow assembly type selected
- Manufacturer and model recorded
- Assembly size recorded
- Assembly serial number recorded
- Installation location identified
Test Equipment and Calibration
This section proves the test kit was current, suitable, and in good condition before any readings were taken.
- Test gauge serial number recorded
- Test gauge calibration date current
- Gauge calibration is within required interval
- Test kit hoses, fittings, and adapters free of visible damage or leakage
- Test equipment identified as suitable for the assembly tested
Field Test Readings
This section captures the actual measured performance of the assembly and is the core evidence behind the pass/fail decision.
- Test method and sequence followed for the assembly type
- First check valve differential pressure reading
- Second check valve differential pressure reading
- Relief valve opening point or air inlet opening point recorded, as applicable
- Shutoff / hold performance verified
- No visible leakage, spitting, or abnormal discharge observed during test
Compliance, Deficiencies, and Sign-Off
This section records the final compliance outcome, any corrective action needed, and the tester’s certification and signature.
- Assembly passed field test
- Deficiencies or non-conformances documented
- Corrective action and retest required
- Tester certification number recorded
- Inspector signature
How to use this template
- 1. Enter the inspection date, site name, service address, water purveyor or AHJ, and the reason for the test before starting the field walk.
- 2. Identify the assembly type, manufacturer, model, size, serial number, and installation location so the report matches the exact device in service.
- 3. Record the test gauge serial number, calibration date, and suitability for the assembly, and stop the test if the kit is out of interval or visibly damaged.
- 4. Perform the field test in the sequence required for the device type and enter each reading exactly as observed, including differential pressure, relief valve opening point, or air inlet opening point where applicable.
- 5. Mark pass or fail, document any deficiency or non-conformance with a clear corrective action, and schedule a retest if the assembly does not meet the required result.
- 6. Finish by entering the tester certification number and signature so the report can be submitted to the purveyor, AHJ, or site compliance file.
Best practices
- Use the exact assembly type on the report before you begin testing so the field sequence matches the device design.
- Record readings to the same precision required by the local program or manufacturer instructions, and do not round away borderline results.
- Photograph the assembly nameplate and any visible leakage, spitting, or abnormal discharge at the time of the test.
- Verify the test kit calibration date before every job, not after a failed result creates a dispute.
- Document the reason for the test, especially when it is a post-repair retest or a seasonal startup inspection.
- Note the installation location precisely enough that another tester can find the same assembly without guessing.
- Separate a true test failure from a site access issue or missing equipment issue so the deficiency is clear and actionable.

Common use cases
Frequently asked questions
Which backflow assemblies does this template cover?
This template is built for field testing reduced pressure (RP), double check (DC), double check detector assembly (DCDA), pressure vacuum breaker (PVB), and spill-resistant vacuum breaker (SVB) devices. It captures the device type first so the tester can follow the correct sequence and record the right readings. If your site uses another assembly type, you can clone the template and add the device-specific test fields.
Who should complete the field test report?
A qualified backflow tester or other authorized inspector should complete the report, depending on local water purveyor or AHJ requirements. The template includes tester certification number and signature fields so the record can stand on its own during review. If a contractor performs the test, the site should still retain the completed report for compliance tracking.
How often should backflow preventers be tested?
Testing frequency is usually set by the water purveyor, AHJ, or local code program, and many sites test annually or after repair, relocation, or suspected failure. This template works for scheduled compliance tests as well as post-maintenance retests. If your jurisdiction requires a different cadence, you can adjust the inspection date logic and reminder workflow.
What compliance rules does this report support?
The report supports documentation practices commonly expected under local cross-connection control programs, water purveyor rules, and AHJ requirements. It also aligns with the recordkeeping style used in regulated maintenance programs where device identification, calibrated test equipment, readings, deficiencies, and corrective action must be traceable. Always confirm the exact local standard before finalizing the form.
Why does the template ask for gauge calibration details?
Backflow test results are only useful if the test kit is current and suitable for the assembly being tested. Recording the gauge serial number, calibration date, and interval helps prove the readings were taken with valid equipment. A current calibration record also reduces disputes when a device fails and needs repair or retest.
What are the most common mistakes this template helps prevent?
Common mistakes include missing the assembly serial number, using an out-of-date test kit, skipping the required test sequence, and recording pass/fail without the actual readings. Another frequent issue is failing to note visible leakage, spitting, or abnormal discharge during the test. This template forces those details into the report so the record is complete enough for review.
Can this template be customized for a water purveyor or contractor workflow?
Yes. You can add permit numbers, customer account identifiers, digital signatures, photo attachments, or a retest scheduling field without changing the core test logic. Many teams also add a dropdown for local AHJ or purveyor name so reports stay standardized across multiple service areas.
How does this compare with a generic inspection form?
A generic inspection form usually captures only a pass/fail result and a few comments, which is not enough for backflow compliance. This template is specific to the device type, test equipment, field readings, and deficiency documentation that reviewers expect. That makes it easier to submit, audit, and defend the report later.
